HOIS'I. AND CONVEYER.

Application filed September 21, 1923. Serial No. 664,064.

To all whom it may concern:

7 Be it known that I, ANsoN P. HoIsrNo- TON, a citizen of the UnitedStates, residing at Powell, in the county of Park and State. oflVyoming, have invented certain new and useful Improvements in Hoistsand Convey-f ers, of which the following isa specification.

The invention relates to a device for hoisting material and conveyingthe same .and is applicable to such uses as loading or emptying cars orsea going vessels or for placing material in storage in buildings,cellars, etc. or removing the same therefrom. The device may be used asa litter carrier in stables and comprises a track formed in readilyassembled sections having a sectional support therefor, diverging legsto support the track and its support; a carrier embodying a tackle blockin its structure havin a pawl and ratchet controlled blocks and also acar rier platform having a winding shaft which may be utilized to hoistmaterial loaded upon a platform. I

Illustrative embodiments of the invention are shown in the accompanyingdrawings, in which 7 Figure 1 shows a side elevation of a track andsupports formed of metal.

Figure 2 is aper'spectiveview of a track support in separated condition.y Figure 3 is a perspective view of a sec- "tion of track.

Figure 4 is an end view of the device shown in Figure 1.

Figure 5 1s a detailed vertlcal section to an enlarged scale taken online 5 .5 of Fig ure 1. s

Figure 6 is a perspective view of a coupling device.

Figure 7 is a perspective view of a form of track and supports formed ofwood.

Figure 8 is an end view partly in'section of the structure of F igure 7drawn to an en-.-- larged scale.

,Figure 9 is a perspective view of a leg receiving channel member, and

Figure 10 is a perspective view of a track splicing member. s

As shown in Figure 1 the device comprises a track support formed ofsections 10 pref-- erably formed of pipe of a suitable diameter as forinstance two inch pipe, the sec- 5 tions being adapted to be joinedtogether means of apiece of smaller pipe 11 permanently secured withinone of the ends of each of the sections 10. To support the sections 10there are shown legs 12 each having a piece of strap iron 13 riveted toits upper end and having the ends deformed as at 1 1. to engage a loop15 secured to the section. The first section to be assembled ispreferably provided with two loops 15 as shown in Figure 2 whilesubsequent sections require but one such loop for their efiicientsupport. Preferably there is placed a section 10 having two of the loops15 at each end of the length of track to be used. 3

The track as shown in Figure 3 is formed of two pieces of angle iron 16placed back to back and secured by pins 17. To secure the successivesections together one end of each section of track is shown as providedwith a plate 18 secured between the angle irons 16 as by means of rivets19 and serving to space theangle iron 16 apart. To maintain this spacinga pin 20 adjacent the op posite end of the section is provided with abushing of a length slightly greater than the thickness of the plate 18over which bushing a notch 21 in the plate 18 of thenext track sectionis adapted to engage. To hang the track section from the section 10there are shown hooks 22 passing through, perforations in the section 10and retained therein as by being headed which hooks are adapted to coactwith rings 23 having projecting port-ions 24 lying in the space be-'tween the angle iron 16 and secured thereto as bycertain of the rivets17.

Goacting with the track there are shown carriers 25, 26, each preferablyformed of side members 27 having upwardly projecting arms 28 eachequipped with a wheel29 adapted to roll upon the track in a manner wellunderstood. Formed with the side members 27 there are shown discs 30perforated to receive an axle 31 upon which are mounted-the pulleyblocks 32.

To hold the load in an elevated position while being transported eachpulley block is preferably provided with a series of ratchet teeth 33which coact with gravity actuated pawls 34E pivoted upon the discs 30 asat 35. To normally hold the pawls in the elevated position there isshown a plate 36 supported upon arms 37 pivoted upon a shaft each paw]passing through alo'op 39 projecting from an arm 37. Spring LO is shownas coiled about the shaft 37 and as having the end A1 anchored inperforations 4-2. The other end of the spring 43 underlying an arm 37 soas to normally lift the pawls 34. An arm A5 is shown projecting from theplate 36 and having an eye 4C6 through which the fall &7 of the ropepasses.

When the load is lifted by means of the rope passing about the blocks 32by a direct downward pull each pawl 34 will be in engagement with itsratchet teeth 33. The spring &0 being held depressed by means of therope and eye 46. hen the load 1S to be lowered the fall 47 will bepulled out of vertical carrying with it the eye 46 there by allowing thespring to lift the pawls 34: whereupon the blocks may be thrown in thereverse direction to lower the load.

To connect two of the carriers 25 there is shown in Figure 6 a couplinghaving an opening 48 which may be placed over the shaft 31 and securedthereto by means of a nut threaded .on the shaft. Projections 49, 50from the coupling plate are provided with perforations 51, 52, throughwhich a coupling pin 53, Figure 1, may be passed and a coupling rod 54having an eye at each end may be engaged with the pins 53. Coupled inthis manner the carriers may pass about a curve in the track in a merelyflexible manner.

To support a load to be carried, a platform 56 is shown as adapted to besupported by straps 57 formed with an eye 58 at their union, which eyesare adapted to engage hooks 59 provided upon the movable blocks 60. Whenthe platform 57 is utilized the fall 47 of the ropes upon the blocks ofthe carriers may be passed about the sheaves 61, 62, upon a shaft 63,centrally journaled below the platform 56. The sheave 62 is shown asprovided with a ratchet 6 and a pawl 65 may be pivoted upon the platformto prevent the unwinding of the fall from the sheaves. A crank 66 isshown upon an end of the shaft for causing its revolution. \Vhen thecrank 66 is turned the platform 56 will be lifted. hen the platform isto be lowered the pawl 65 may be thrown out of engagement with itsratchet and the falls 41-7 may be pulled out of vertical to release thepawls 3% when the platform will be allowed to lower by gravity. In thisform of the device to be used independently of other structures braces67 are preferably provided in one or more of the spans. The bracing ofone span will usually be sufficient. In Figures 7 to 10 inclusive thereis shown a form of the track and supports which may be constructed ofwood as for instance of 2 X Is. In this form of the device the tracksections 68 are provided with hooks 69 to engage with the eyes 70carried by the track sections 7L To join the ends of the section 68there is shown a channel 72 perforated as at 73 for passage of one ofthe hooks 69. The hooks 69 at the joints betweenthe sections are shownas lying in semi-cylindrical depressions in the end of the section 68.To receive the ends of supporting legs 74; there are shown wings 75struck outwardly from the channels 72 and the ends of the legs 74c areshown in Figure 8 as chamfered at 76 to coact with the wings 75.

To joint the sections of'track 71 there is shown a rectangular hollowsleeve 77 of internal dimensions appropriate to receive the ends of thetrack sections. A hole 78 is shown in the sleeve to receive one of theeyes 70. To receive the wear of the wheels upon the carriers, shown indotted linein Figure 8, the upper surface of the track section 71adjacent to the outer edges are shown as faced with strap iron 79 thethick ness of which is equal to the-thickness of the walls of thesleeves 77.

When it is desired to use the device for unloading material from freightcars one section of support and track may be assembled in one end of thecar when the carrier may be put in place and other sections added. Thedevice may be thus very quickly assembled and material may be thusreadily wheeled to the door of the car for dumping into awaitingvehicle.

The device may also be set up in vegetable cellars where largequantities of vegetables, as potatoes, are stored, so thatthe vegetablesmay be readily moved in and out when necessary, and may be readilyremoved from one place of use to another.

Minor changes may be made in the physical embodiment of the inventionwithout departing from its spirit.
